how to approach making these granules?
So I found another way to approach this. Using the particle system in blender and using the hair type, I just sampled a granule that I made quickly and emitted it over an object which would have the same shape of the granule inside the bottle.



As you can see in the image, this seem like a decent approach, I still have to play around with the settings and the texture of the granule but i think it will get the job done nicely :)
